This standard and ISO address the same subject matter but differ in technical content. Errors in exposure are cumulative with time. This f3045 is not included in any packages. Certain materials are susceptible to the influence of humidity. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.
The severity of the exposures in both time and temperature determines the extent and type of change that takes place. Proceed to Checkout Continue Shopping. We have no amendments or corrections for this standard.
Specific properties and failure or lifetime criteria for these properties are typically chosen for the evaluation of thermal endurance. A plastic material is not necessarily degraded by exposure to elevated temperatures.

Only the procedure d345 heat exposure is specified. Recommended procedures for determining the thermal aging characteristics of a material using a series of elevated temperatures for the purpose of estimating endurance time to a defined property change at a lower temperature are also described; the applicability of the Arrhenius relation for making predictions to other temperatures, is assumed in this case.
Therefore, for any application of the CUT or the TI temperature index to be valid, either the thermal aging program must duplicate the intended thermal exposure conditions of the end product, or the Arrhenius relation must apply.

Mechanical properties, such as flexural properties, are sensitive to heat degradation and may change at a more rapid rate. If the document is revised or amended, you will be notified by email. Add to Alert PDF. Standards Subsctiption may be the perfect solution. Historical Version s – view previous versions of standard. These asstm should be avoided both in the range of aging temperatures used, as well as in extrapolation of the lifeline.
Subscription pricing is determined by: Factors that affect the reproducibility of data are the degree of temperature control of the enclosure, humidity of the oven, air velocity over the specimen, and period d3054 exposure.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. With semi-crystalline and highly crystalline polymers, elevated temperatures may cause significant changes to the morphology of the material, invalidating or compromising that assumption.
Different properties, mechanical or electrical, may not change at the same rate. This zstm is also available to be included in Standards Subscriptions. The property of interest is measured at room temperature. You may delete a document from your Alert Profile at any time.
The effect of elevated temperature on any particular property is determined by selection of the appropriate test method and test specimens for that property. Already Subscribed to this document. Your Alert Profile lists the documents wstm will be monitored.

On the contrary, this practice is designed d045 provide data which can be used for such comparative purposes. For instance, the arc resistance of thermosetting compounds improves up to the carbonization point of the material. Work Item s – proposed revisions of this standard. You can sstm and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server.
However, extended periods of exposure of plastics to elevated temperatures will generally cause some degradation, with progressive changes in physical properties. The property of interest is measured at room temperature.
